How many moles of oxygen must be placed
in a 3.00 l container to exert a pressure of 2.00 atm at 25.0°c?

i did (2.00)(3.00) divded by (0.0821) (298) and i'm still getting the answer as 27,700 or something like that. i know i did the equation right? but, i keep getting the wrong answer. .

Tell me the iupac name of the following compounds:

Plzz a sample of table sugar (sucrose, c12h22o11) has a mass of 7.801 g. ● a) calculate the number of moles of c12h22o11 in the sample b) calculate the number of moles of each element in c12h22o11 (number of moles of c, number of moles of h & number of moles of o) in the sample. (use your answer from part a as your starting point.) show your work and highlight your final answer. calculate the number of atoms of each element in c12h22o11 (number of atoms of c, number of atoms of h & number of atoms of o) in the sample. (use your answers from part b as your starting for each element.) show your work and highlight your final answer.
